ipsec tunnel <n> command, issued from

tunnel mode. This is denoted by
config-ipsec-tun in the prompt.
The identifier number for tunnel entries starts at
0 and increments by one.
To determine the next tunnel number for a new entry, run
ipsec tunnel ? and
TNSR will print the existing tunnel ID numbers.
This command creates an IPsec tunnel with an identifier of
tnsr(config)# ipsec tunnel 0 tnsr(config-ipsec-tun)#
The remainder of the configuration is covered in the following sections.
